$NVDA $AAPL $AMZN $GOOGL $MU — Markets opened Monday with a risk-on/risk-off tug: Treasury-yield moves tied to buyback talk and a forthcoming Jackson Hole keynote pushed bond volatility lower even as Dell’s 235% YTD surge and looming tech earnings (Micron, Alphabet, Amazon, Nvidia) kept equity attention focused on concentrated, event-driven bets. Analysts flag clashes—buyback talk that moves yields versus views that it’s not a market-changing ‘bazooka’, and crowded institutional positioning in richly priced names like SpaceX and Dell.
